The interaction of age and cognitive representations in predicting blood pressure.

The purpose of this study was to investigate the interaction of age and cognitive representations of hypertension in predicting blood pressure. A model of illness self-regulation was used as the theoretical framework for the study. Secondary analysis of data collected from 224 hypertensive adult outpatients was conducted to assess five constructs of illness. ANOVA results indicated that older adults reported fewer hypertension-related symptoms than younger- and middle-aged adults, and that younger adults reported fewer health behaviors to control hypertension than did middle-aged and older adults. Results of hierarchical multiple regression models indicated that after adjusting for effects of demographic factors, no single cognitive representation construct was a significant predictor of blood pressure. The interactions of age and three cognitive representation constructs were, however, significant predictors of blood pressure. For younger adults, increases in the perceived Consequences, Control, and Timeline for hypertension were predictive of decreases in hypertension, although for older adults increased perceptions of control were associated with increased blood pressure.

Systematic methods to enhance diversity knowledge gained: a proposed path to professional richness.

Faculty members in nursing schools have the responsibility to provide learning experiences for students that have the potential to solidly link indicators of professional richness, knowledge gained about diversity, enhanced critical thinking skills, ethical reasoning and decision-making. The challenge then is for faculty members to implement systematic methods to ensure that students are exposed to in- and out-of classroom experiences that result in measurable outcomes indicating a strong association between what a student is expected to learn and the diversity knowledge gained. The purpose of this study is to describe the effect of a target intervention derived from synthesizing multiple theories (social, cognitive, moral and ethical) and learning experiences on students' perception of global diversity. Two independent cohorts of senior nursing students, (control group, N = 65 and experimental group, N = 55) were taught a required undergraduate course: Societal Health Issues (SHI) with the same objectives over two consecutive years. Drastic and remarkable differences were demonstrated using separate multiple regression analyses of the experimental group (adjusted R2 change of 47% (F = 11.123, (df1 = 4; df2 = 47), p = .000) and control group (adjusted R2 change of 1% (F = 1.36, (df1 = 4; df2 = 52), p = .259). This study suggests preliminary empirical support for exploring how conceptual frameworks may guide faculty to consider pushing beyond traditional teaching methods to develop and organize systematic methods for infusing diversity content in courses.

Examination of factor structure of the cognitive representations of hypertension scale for ethnic equivalence.

The major purpose of this analysis was to examine the factor structure of separate interpretive dimensions of the Cognitive Representation of Hypertension Scales (CRHTN) for ethnic equivalence. The CRHTN is a theoretically derived measurement of individualized experience of hypertension assessed along three cognitive interpretive dimensions: perceptions, preferences and possibilities. The sample for this study was recruited from a university-based hypertension clinic, a Veterans Administration ambulatory service, and a large urban-based HMO. Analysis of data through confirmatory factor analysis techniques across both samples provided evidence for construct validity of a five-factor model along three dimensions: perceptions, preferences and possibilities. However, multigroup analyses suggest the model may not equally describe cognitive representations of hypertension for different ethnic groups. Differences in fit of the theoretical model to data from two different ethnic groups is discussed. Findings from this study provide a basis for development of culturally sensitive and appropriate cognitive strengthening strategies to influence behavioral outcomes for hypertension management.

Reliability and validity of the Lifestyle Hypertension Cognitive Representations scale.

Lifestyle behaviors are thought to be guided by cognitive or mental representations that function to structure knowledge related to behaviors and goals. The Lifestyle Hypertension Cognitive Representations (LHCR) scale was developed to measure cognitions about hypertension-related behaviors on three cognitive dimensions. Items were derived from a literature and content analysis of qualitative data from 124 hypertensive patients. The three dimensions based on cognitive research generated subscales for perceptions (recognition), preferences (importance), and possibilities (future usefulness). Internal consistency reliability was adequate with alpha coefficients near .80 for composite and subscales in two independent culturally diverse samples. The total-to-total correlation with a related construct was low. One-way ANOVA demonstrated the expected results for known group differences by severity of blood pressure state for the composite, perceptions and possibilities subscales of the LHCR. Multiple regression revealed that the perceptions and possibilities subscales interacted to predict diastolic blood pressure. Together with socio-demographic variables explained the variance for a total of 25%. Further work is indicated to determine the instrument's usefulness as a basis for interventions to reduce blood pressure.
